Another Pulley Question

[BackInBlack]

Couldn't find the answer with search. I am running a 2.75 upper and stock lower. Think I am getting a little bit of belt slip. Do I need to get the 4 piece pulley kit from billetflow or can I just use 1 pulley and be good?

only the snub idler is supposed to help with belt slip, the other idlers are because the stock ones have been known to fall apart.

I recently seen this on another post with just the upper and snub, and from experience, I had slip with my setup also, that's why I went with the 4 piece Billetflows. You will slip if you don't.

alright, i got the BilletFlow 2.76 with 100mm snub idler, MAF.ia and tuned by Shawn at AED. the a/f came out perfect pretty much, right at 11.8-12.0. it made 442 rwhp / 453 rwtq SAE or 453 rwhp / 464 rwtq STD. I have a belt slip (going from almost 15# @ 5000 rpm to about 12#'s @ 6000 and then slips to just under 12 by 6400. Also, my fuel pumps were pegged pretty much by 5000 rpm.

what can i do to try to eliminate the slip i have? im currently running a gates (74 5/8") belt. also, what can i do for the fuel? Im not running lean on the topend, which is good.

The belt slip is confusing. I thought you needed at stock 75.1 belt for a 2.76, snub idler and pulleys. :shrug:

As far as fuel, get a BAP. It plenty for most applications.
